Agreed. I think in a number of years, maybe only 5, solar, wind, etc will provide a surplus of energy needs. I think the investment question begins to lean towards energy storage to smooth out the load? The investment question I’m asking now is what is the dominate storage technology? Does it even exist yet?
I think your timetable is over optimistic, it will take time, maybe decades to switch off fossil fuels. There are many alternatives to battery storage, specially for large scale projects like pumped hydro. The other alternative is long distance DC transmission but that is a technology that still needs a lot of development to make it economically viable.
I agree with telegraph that there are lots of hurdles. Where I disagree with telegraph is in the ability of humans to surmount these hurdles. Airplanes weighing tons fly and we have proof that the Moon is not made of green cheese, we have been there!

My grandmother didn’t have electricity, an elevator, or a telephone. Back in the day bakers baked the dough that housewives knead at home. She made lovely potato bread. Her kitchen was coal powered. And that was less than 100 years ago.
